Quick Overview

iHow this is made

This summary is generated from the verified data on this profile: services, service area, credentials, warranty terms and the company's Google review record. It is reviewed by an editor before publishing and refreshed whenever the underlying data changes. Nothing here is asserted that is not stated elsewhere on this page.

Editorial Standards

Olshan Foundation Repair holds 4.8 stars from 2,094 Google reviews, read October 21, 2026, and the reviews keep describing the same experience: crews that arrive when promised, explain each step and leave the yard tidy. The company works from 1614 Bluebank Rd in Northwest Dallas and says it has served Texas homeowners since 1933. Foundation work is its core, but its website also lists French drains, surface drains, downspout extensions, sump pump basins and pumps, and crawl space encapsulation with a moisture barrier liner. Free in-home evaluations, a lifetime transferable warranty on its Cable Lock ST Plus piers, and financing with plans from $125 a month are all stated on the site.

Editorial Review

Our Take on Olshan Foundation Repair

Olshan's 4.8 stars across 2,094 Google reviews is a large and steady record, and the praise is consistent about punctual crews and clean job sites. Its drainage and crawl space menu is genuine, though the warranty it advertises covers the foundation system and no drainage warranty is stated. Expect a foundation-first company that treats water control as part of keeping the structure stable.

What We Like

  • 4.8 stars from 2,094 Google reviews, read October 21, 2026
  • Website lists French, surface and subsurface drains, plus sump pump basins and pumps
  • Crawl space encapsulation with a SafeSeal liner, dehumidifier and optional air exchange
  • Lifetime transferable warranty available on its Cable Lock ST Plus foundation system
  • Free in-home evaluation, 0% financing options with approved credit, plans from $125 a month

Things to Consider

  • The stated warranty covers foundation piering, and no drainage warranty is described; transfer needs a fee and paperwork within 90 days.
  • Its site uses the name Olshan Foundation Solutions across about 22 Texas locations, so confirm the Dallas crew will handle your drainage job.
  • One reviewer paid more after the crew corrected the first plan, and the site hours (8 AM to 5 PM) differ from Google (to 8 PM weekdays).

Company Background

About Olshan Foundation Repair

Olshan Foundation Repair has 4.8 stars from 2,094 Google reviews, read October 21, 2026, and the comments repeat the same few things: crews that arrive on time, explain each step and leave the property as they found it. One homeowner described a two-day pier job in which Luis re-checked every pier location and explained each change before work began. Another praised Kevin and Armando for spotting that the first plan would cause trouble later and correcting it. Oscar's crew drew thanks for raising a foundation and putting everything back. Reviewers also name Dan Steele, who inspects homes for the company.

The office is at 1614 Bluebank Rd in Northwest Dallas, and the company says it has served Texas homeowners since 1933. Its water side is a real part of the offer. The website lists French drains, double barrel drains, surface drains, downspout extensions, sump pump basins and pumps, and crawl space encapsulation with a SafeSeal liner, a dehumidifier and an optional air exchange system. It also sells a foundation watering system meant for drought periods. Structural work uses its patented Cable Lock ST Plus piers, backed by an available lifetime warranty that transfers to a new owner if the paperwork and fee are handled within 90 days of a sale.

The stated service area runs from Dallas to Plano, Richardson, Irving, Garland, Frisco, McKinney, Arlington and Fort Worth, with Highland Park and Oak Cliff named as examples. Google lists hours of 8 AM to 8 PM on weekdays and 8 AM to 1 PM on Saturday, closed Sunday. Estimates are free, and financing includes 0% interest options with approved credit.

One fair note from the reviews: Lorrie gave four stars because the corrected plan cost more, though she said she preferred to have the job done right the first time. This company suits homeowners whose water trouble is tied to a settling slab or a damp crawl space. It suits less well anyone who wants only a small interior sealing job. Texas has no state waterproofing contractor licence, so check insurance, the Better Business Bureau record and the Dallas city permit rules for structural work. For plumbing work, use the Texas State Board of Plumbing Examiners lookup. Ask who designs the drainage plan and whether any drainage work carries its own warranty.

Olshan Foundation Repair FAQs

  • Do waterproofing contractors need a licence in Dallas, Texas?

    Texas has no state licence specific to waterproofing contractors, so you need to check the company yourself. Olshan Foundation Repair does not publish a licence number on its website. Ask for proof of insurance, look up its Better Business Bureau record (its site reports an A+ rating), and confirm the Dallas city permit rules for structural work. For plumbing work, use the Texas State Board of Plumbing Examiners lookup.

  • What are Olshan Foundation Repair's hours in Dallas, and is there emergency service?

    Google lists the Dallas office as open 8 AM to 8 PM Monday to Friday and 8 AM to 1 PM on Saturday, closed Sunday. Olshan's own site shows 8 AM to 5 PM, so call (972) 238-1600 to confirm. The website does not mention emergency or 24-hour call-outs. Free estimates and in-home evaluations can be requested online or by phone.

  • Does Olshan Foundation Repair offer a warranty and financing in Dallas?

    Yes to both, with limits. Its Cable Lock ST Plus foundation system has an available lifetime warranty that transfers to a new owner if the form, fee and paperwork are completed within 90 days of the sale. No drainage warranty is described on its website. Financing offers 0% interest options with approved credit and plans starting at $125 a month.
